Description
Technical field
The utility model belongs to the technical field of Medical Devices, and in particular to a kind of domestic type oesophageal dilator.
Background technology
Lemostenosis is esophageal lesion surgical operation, the common postoperative complications of therapeutic endoscopy, is also seen sick around oesophagus
Become and cicatricial stricture formed etc. is damaged by outside compressing, Esophageal Mucosa, currently used treatment method is mega-esophagus and food
Pipe holder implantation.Commonly stretched in oesophagus and expanded with air bag, still, typically once expansion can only use fixation
A kind of expander of size, after completing expansion, then the expander of next size is changed, in general, the size of expander has
7mm, 9mm, 11mm, 12mm, 13mm and 15mm are several, the oesophagus width of most of patient between two kinds of sizes expander it
Between, expansion effect is not had using the expander of reduced size, but larger-size expander is but difficult to be put into oesophagus.Using
Method be to be expanded repeatedly using the expander of reduced size, until the expander of large-size can be accommodated, some patientss need
Multiple or even tens of expansion of row, pole HD is caused to the economy and life of patient.In addition, air bag quality is softer, when slotting
When entering oesophagus stenosis, air bag can be deformed so that and expansion effect is had a greatly reduced quality, but uses the air bag expansion of hard,
Esophageal Mucosa is easily damaged again, causes the complication such as bleeding.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided one kind is in expanding mistake
Gradually change the expanding width of expander in journey and the domestic type oesophageal dilator of expander expansion hardness can be changed.
To realize above-mentioned technical purpose, the technical scheme that the utility model is taken is：
A kind of domestic type oesophageal dilator, wherein：Including connecting tube, connecting tube front end is provided with water pocket, and rear end is connected with
Injector, the front end of connecting tube are inserted in water pocket, several support bars are hinged with the connecting tube in water pocket, support bar passes through drawing
Line is connected with being arranged on the regulation handle of connecting tube rear end, and regulation handle can be slided in connecting tube, and regulation handle passes through drawing
Line struts or closed support bar, and when support bar closes, support bar is affixed in connecting tube, when support bar struts, supports rod end
Portion is withstood on water pocket inwall, and several imbibition expanding materials are fixed with water pocket outer wall, and imbibition expanding material is smooth outer surface
Non-porous, the internal material in alveolate texture, connected with water pocket inside imbibition expanding material, injector can be by connecting tube to water
Intracapsular water filling, fills water pocket.
To optimize above-mentioned technical proposal, the concrete measure taken also includes：
The rear end of above-mentioned support bar is hinged with connecting tube, and front end is free end, and the front end of support bar connects drag wire.
Water injection hole and cable hole are provided with above-mentioned connecting tube, water injection hole and cable hole are not come round mutually, water injection hole one end
Connected with water pocket, the other end is connected with injector, and drag wire one end is connected with support bar, and the other end passes through cable hole and regulation hand
Handle connects.
Above-mentioned imbibition expanding material is water-absorbing resin.
The rotational angle range of above-mentioned support bar is 0 ° to 90 °.
Above-mentioned support bar front end is round and smooth.
Instruction block and rear instruction block, preceding instruction block are away from expander front end distance before being provided with above-mentioned connecting tube
15cm, it is rear to indicate that block indicates that block distance is 25cm away from preceding.
5cm is provided with a tangible scale projection arrived between above-mentioned preceding instruction block and rear instruction block.
Above-mentioned connecting tube rear portion is provided with sliding groove, and regulation handle is stuck on sliding groove and slid axially.
Existing air bag expansion is changed to water balloon dilator by the utility model, and water pocket is bigger compared with air bag weight, can pass through
Weight is to slip below oesophagus, and without being pushed hard with hand, more difficult injury oesophagus, water pocket extrudes at by lemostenosis
When, deformation is also smaller, can be preferably to mega-esophagus.Water balloon dilator is used to provide water source, this reality for imbibition expanding material
Supplied water and expanded to imbibition expanding material with new water pocket, the width of imbibition intumescent material swells is noticeably greater than water pocket because dehydration subtracts
Small width, therefore, water pocket overall width can gradually increase over time, and this process can continue dozens of minutes, at this
In, patient can persistently pump oesophageal dilator and oesophagus is expanded, and oesophagus width is gradually increased, process is gentle, no
Very big sense of discomfort can be produced.Several support bars that can be strutted are provided with connecting tube in water pocket, support bar passes through setting
Drag wire in connecting tube is connected with regulation handle, when regulation handle slides backward, before drag wire can affect support bar
End rotates, so that support bar struts, withstands in water pocket, water pocket is resisted the capability improving of external pressure.Carried so as to reach
The effect of high expander expansion hardness.In actual use, patient can voluntarily choose whether to use support bar, can also make
Support bar is enabled during, is first expanded back and forth for several times with soft water pocket, after acquirement certain effect to be expanded, then support bar is supportted
Open, further expansion for several times, can solve the problems, such as that the soft soft expansion effect of water pocket matter is limited, can also solve well in this way
The problem of certainly directly easily being damaged using Esophageal Mucosa caused by hard material expansion.
